Secure Storage (Keychain/Keystore)

Secure storage of tokens/secrets/etc. and possibly the ability to share those across SDKs.

Preferences (UserDefaults/Preferences)

Reachability

Encoding (HmacSHA256)

Utilities to support things like

• Cosmos DB: Constructing the hashed token signature for a master token
• Notification Hubs SAS

Logging

Unified API for all logging across all SDKs. All SDKs must use these logging functions for any info, warning, debug, error, etc. messages. This will simplify testing and validating we're not logging any information we shouldn't be.

API

• Error
• Warning
• Info (verbose)
• Debug?
• Flag for enabling logging level
